Can anyone point me in the direction of a thread (if one exists - can't find one) of how to repair (I really mean replace) the lugs on speakers grills such as those on MS150 ?

I've sourced some 10mm rawlplugs that fit quite snugly into the holes and I'm think of filing down the stubs of the lugs that have broken off, then super gluing the rawlplugs onto the filed down stubs.... Not convinced it's going to be a quality job!

If no thread exists then I'm open to suggestions to a better method....

Cheers

You are on the right track, but use epoxy to glue the plugs to the stubs,

Thanks. Why epoxy? Is it stronger than super glue?

For that kind of plastic (and most other jobs) superglue is actually quite brittle and doesn't bond well.  Araldite or 2-part epoxy bonds to most surfaces and as it's spread over a larger surface area is much stronger.  Allow it to 'cure' for 2 days to achieve maximum strength before applying any stress to the joints.

You can't beat Araldite.

I also use Araldite. The slow setting type is the strongest.

Never used Araldite, but 2 part epoxy I use frequently for jobs like this. Just add a small amount to the, to be glued, surface, wait half an hour, and then you can build up more around the plug. And as Dave says wait 2 days before putting stress on it.

Araldite is a 2-component Epoxy glue.
